Intérêts de recherche

My research investigates the physical flow processes (e.g., flow resistance, generation and advection of coherent flow structures, sediment transport) occurring in rivers and open channels and the relationships between flow structure and aquatic biota (i.e., fish). Many of my projects involve the characterisation of flow structure in open-channels.

Activités de collaboration internationale

  • Principal investigator. (2015-2017). United States. I have continuing collaborations with T. Castro-Santos a well-known fish biologist working at the USGS-S.O. Conte Anadromous Fish Research Center (CAFRC) in MA, USA. In 2015, we conducted experiments on fish passage over baffles of varying geometry at the CAFRC. We have as well submitted a paper together with E. Enders investigating fish preference for vertical- and horizontal-baffled channels (CV:JA1).
